1. At 2330/I, 5 August 1952, A/3C Lloyd West and A/1C Walter Cutowski, 1956-1AACS Detachment, while corssing the ramp on their way to work at the Haneda Air ForceBase control tower, (35~33�N-139~45�E), sighted an exceptionally bright light in thesky to the NE of Haneda Air Force Base. Upon reporting for duty, they brought theobject to the attention of A/2C Walter Jackson and A/3C George LaGaase, who had notpreviously noticed it because the operating load had been keeping their attentionelsewhere.

a. The four operators agreed on the appearance of the object and watchedit through 7 x 50 binoculars for a total period of about 50 minutes to 1 hour. Thelight was described as circular in shape, with brilliance appearing to be constantacross the face. The light appeared to be a portion of a large round dark shape whichwas about four times the diameter of the light. When the object was close enough fordetails to be seen, a smaller less-brilliant light could be seen at the lower lefthandedge, with two or three more dim lights running tin a curved line along the restof lower edge of the dark shape. Only the lower portion of the darker shape could bedetermined, due to the lighter sky which was believed to have blended with the upperside of the object. NO rotation was noticed. NO sound was heard.

b. The object faded twice to the East, then returned. Observers were uncertainwhether disappearance was due to a dimming of the lights, rotation of object,or to the object moving away at terrific speed, since at times of fading, the objectwas difficult to follow closely, except as a small light. Observers did agree thatwhen close, the object did appear to move horizontally, warying apparent position andspeed slightly.

c. Three of the operators indicated the size of the light, when closest tothe tower, was approximately the same as the small ceiling balloons (30 grams, appear-ing 24 inches in diameter) when launched from the weather station, located at about2000 feet from the tower. This would make the size of the central light about 50 feetin diameter, when at the 10 miles distance tracked by GCI. At the greatest distance,the size of the light appeared slightly larger than Venus, approximately due East ofHaneda and slightly brighter. A lighted weather balloon was launched at 2400 hours.The balloon�s light was described as extremely dim and yellow, when compared to thebrilliant blue white light of the object. Observers stated that their eyes wouldfatigue rapidly when they attempted to concentrate their vision on the object.

d. Shiroi GCI was contacted, (35 deg 49�N-140 deg 02�E), and after visual vectorswere given, were able to track the object. An F-94 was in turn scrambled for an at-tempted intercept.

e. The control tower at Tachikawa Air Force Base called Haneda tower at ap-proximately 2350/I to bring their attention to a brilliant white light over Tokyo Bay.The tower replied that it had been in view for some time and that it was being checked.

f. A C-54 entering Haneda traffic was requested to check the object. Thepilot replied that it looked like a brilliant star and dismissed the sighting as such.

g. The F-94 appeared over Haneda just before the C-54 landed. After theF-94 turned North, the tower called Shiroi to direct the F-94 to turn right. No visualcontact was made by the F-94.

h. The F-94 was vectored to the radar contact maintained by the Shiroi GCI.A radar contact was made by the F-94, but was lost after 90 seconds. Soon after lossof radar contact by Shiroi and the F-94, the tower lost visual contact as the objecteither faded, moved away, or was obstructed by clouds.

2. Site #4, 528th Aircraft Control and Warning Group, located at Shiroi AirForce Base, was notified of the location of the unidentified object soon after thefirst visual contact by Haneda tower. The CPS-1 radar is normally operated at maximumrange, and contact was attempted on both high and low beams by Lt. Rawlins, the con-troller then on duty. Three or four blips were noted at a position 050 deg bearing fromHaneda, as reported by the tower, but no definite movement could be ascertained, andno Height/Range contact could be made with the CPS-4 due to ground clutter.

a. Lt. Albert reported for duty at 2345/I, and was soon able to make radarcontact on the 50 mile high beam. An F-94 was scrambled to investigate. The objectat this time had left the ground clutter and could be tracked at varying speeds in aright orbit. Although impossible to accurately estimate speed, Lt. Albert gave arough estimate of from 100-150 knots, stopping and hovering occasionally, and a maximumspeed during the second orbit (just before F-94 was vectored in) of possibly 250-300knots. At approximately 0012/I the object reportedly broke into three smaller contactsmaintaining an interval of about 1/4 mile, with one contact remaining somewhat brighter.The F-94 was vectored on this object, reporting weak contact at 0015/I and loss of con-tact at 0018/I. Within a few seconds, both the F-94 and the object entered the groundclutter and were not seen again.

b. The blips on the CPS-1 were described as small and relatively weak, butsharply defined. The brightness varied somewhat, and at one time appeared very brightas the object appeared to be in a fairly sharp turn at higher speed than previouslynoted. Both recorded orbits were in approximately the same position, with the objectmoving and occasionally hovering in one position for several sweeps (4 RPM). Surveil-lance of area was made for an extended period of time and no further contact was made.

c. The ADCC Controller at Johnson Air Force Base was kept informed of theincident at it took place. Personnel at Site #4 attempted unsuccessfully to makevisual contact with the object, which at times was less than ten miles distance fromShiroi Air Force Base. Radar was functioning normally before and after the incident.

3. The F-94B with 1st Lt. Wesley R. Holder as pilot and 1st Lt. Aaron Jones asradar operator, was scrambled at approximately 2355/I. There was a slight delay in be-coming airborne due to fuel system trouble during run-up. Aircraft became airborne at0003/I and was directed to make a search from Haneda Air Force Base northeast overTokyo Bay. No visual contact was made at any time.

a. The F-94 crew reported exceptional visibility in the air, with a very thincloud layer at 14,000 to 16,000 feet and one or two isolated patches of thin clouds low-er. The C-54 in the pattern at Haneda Air Force Base was very clearly seen. The onlystars seen at a low elevation were the North Star and Venus. As the F-94 headed North,the Control Tower asked GCI to vector the F-94 toward the east. Looking off their rightforward quadrant and turning in the direction requested, the F-94 was still unable tosee anything unusual.

b. As the F-94 orbited to the right at approximately 330 knots T.A.S., theGCI radar re-established contact with the object and vectored the F-94 on a course of320 deg. GCI called the object at 11 o'clock to the F-94 at 4 miles. At this time theF-94 managed to make a weak contact at 10 deg port, 10 deg low, at a range of 6,000 yards.

c. The radar contact at approximately 35 deg 7'N-139 deg 56'E, was described as weakand small but distinct and definable from the ground clutter encountered. The radaroperator, Lt. Jones, was very busy, maintaining the weak contact by manual control. Asthe object moved across the scope from the port to starboard, it appeared to increasespeed and Lt. Jones called for a hard right turn. As the aircraft turned, the objectappeared to suddenly accelerate and disappeared rapidly from the scope on a course of

131389

PAGE OF PAGES





approximately 055 deg. Contact was maintained for approximately 90 seconds. No furtherreturns were found. In a search pattern, the pilot checked the area very thoroughlyfor any visual signs without success.

d. The APG-33 radar is checked before and after every mission and appearedto be working normally. The blip was described as definitely an airborne target andbehaved as a bona-fide target, except when it appeared to accelerate off the rightedge of the scope. The overcast was extremely thin, and all objects in the area couldbe seen clearly. The F-94 crew stated that there was no possibility of any radar con-tact from any of the clouds in the area at that time.

4. Haneda weather at time of slighting was recorded as 2500 scattered, 16000broken, 15 miles visibility, with wind SSE at 11 mph. Weather reported by the per-sonnel involved in the incident was thin scattered to broken at 14,000-16,000 feet,generally thin enough to allow almost full brilliance of the moon to shines through.One or two thin scattered puffs were reported by the F-94 crew with none reported byHaneda tower. The weather moving in from the southwest was lower broken clouds suf-ficient to obscure the moon as the clouds moved over Tokyo Bay about 0045/I to 0100/I.Visibility was reported as exceptional with Mount Fuji (60 nautical miles to the west)clearly discernable. Scattered thunderstorm activity was reported in the mountains tothe Northwest of the Tokyo area. Temperature recorded at Haneda was 78 deg, Dew Point 73with altimeter setting of 29.81 inches.

5. The personnel, involved were all serious, intelligent, and completely coopera-tive.

a. Tower personnel cross-checked all known factors constantly and did notattempt to make any inferences in the sighting. Object is believed to have been re-ported exactly as they saw it.

b. Lt. Albert, GCI Controller at the Shiroi site, has had considerable ex-perience under all conditions and thoroughly understands the capabilities of the CPS-1radar. His statement was that the object was a bona-fide moving target, though some-what weaker than that normally obtained from a single jet fighter.

c. Lt. Jones, F-94 radar operator, has had about seven years experiencewith airborne radar equipment. He states that the object was a bona-fide target, andthat to his knowledge, there was nothing within a area of 15-20 miles that could givea radar echo.

COMMENTS BY PREPARING OFFICER:

1. The ten minute difference in time between the statement by Lt. Albert, 528thAC & W Sq., and that reported by other personnel concerned, is believed to be a typo-graphical error, since the statement agrees on every other portion of the sighting.

2. The map grid coordinates listed on 35th Fighter Interceptor Wing Form 112,IR-1-52, are in error, since the area of contact was as shown in Inclosure #5. Errormay have been due to a mis-reading by the original debriefing officer.

3. This is the first sighting in the Far East which combined positive visualand radar contact over an extended period of time. The following items may have somebearing on this sighting:

a. On the night of the incident, there was a full moon. The F-94 crew re-ported exceptional visibility and stated that the upper cloud layer did not appreciablyaffect the brilliancy of the moonlight. Reflections off the water were considered as

131390

69




PAGE OF PAGES





sufficient to form secondary reflections off the lower clouds. Isolated patches ofthin clouds were reported by the F-94 crew as being at approximately 4000 feet, withfairly strong reflections making them visible. These clouds were not reported to bevisible by the control tower personnel. A/3C LaGasse reported that as he returned tothe barracks, he noticed that the object seemed somewhat higher in the sky than pre-viously, and that he noticed at the same time that the moon seemed proportionatelyhigher in elevation.

b. There was some thunderstorm activity in the mountains to the northwestof Tokyo. Although lower broken clouds later moved over Tokyo Bay, there was noreported electrical activity or vertical development in these clouds. Visibility wasapproximately the same as earlier.

c. The only objects reported in the area at the time of sighting were theC-54 landing at Haneda and the weather balloon launched by the Haneda weather stationat 2400/1. Both were continually in sight of control tower personnel. Venus waslocated low on the horizon and was definitely identified by the Tower, the GCI Site,and the F-94 crew.

d. According to the radar tracking, the object should have passed very closeto Site #4 at Shiroi. A constant search of the area by personnel at the site, and thethorough search by the F-94 without visual contact indicates possible moonlight re-flections, since the object was visible to the tower personnel at both Haneda and atTachikawa, located 30 miles to the west. The azimuth of the moon at this time was189 deg, with an elevation of approximately 36 deg. A secondary reflection off a cloud couldconceivably be bright to observers to the south or west, while the remainder of thecloud could block the reflection from above and to the north.

e. The F-94 crew evidently made an extremely thorough search over the area,and appeared to be perplexed that they had been unable to make visual contact, sinceeverything within 20 to 25 miles was easily visible. Flying at 5,000 feet, they couldspot the isolated lower cloud patches. Failure to sight the object could only be dueto the light being on the lower surface of the object, or reflected in a narrow beamtoward the south and west.

f. The strange appearance could be attributed to a localized blinding effectcausing the illusion of a darker form, particularly with the lower scattered lights togive an illusion of an outline.

g. Although many sightings might be attributed to visual and electrical re-flections off ionized areas in the atmosphere, the near-perfect visibility on the nightof the sighting, together with the circular orbit of the object would tend to disprovethis theory.

The first time I noticed the intense bright light over the Bay, was whilecrossing the ramp on our way to the tower. At first we thought it was an air-craft with landing lights on, but as we kept watching we noticed it wasn't mov-ing. When we were about half way across the ramp it disappeared for the firsttime and returned to approximately the same spot about 15 seconds later.

After we got in the tower I started looking at it with binoculars, whichmade the object much clearer. Around the bright white light in the middle,there was a darker object which stood out against the sky, having little whitelights along the outer edge, and a glare around the whole thing.

I watched it disappear twice through the glasses. It seemed to travel tothe East and gaining altitude at a very fast speed, much faster than any jet.Every time it disappeared it returned again, except for the last time when thejets were around. It seemed to know they were there.

As for an estimate on the size of the object----I couldn't even guess.

I know it wasn't a star, weather balloons or Venus, because I compared itwith all three.

When we first saw it, we estimated it to be at about 5,000 feet. Wecouldn't estimate the distance because of the angle we were looking at itand the brightness. It was to the NNE of the field.

I watched it from 11:30 to 12:30, it was very clear in the east untilthen. The bright light disappeared again at about 12:30 and we lost sightof it due to the broken clouds that moved in at that time. We kept lookingfor it whenever the clouds broke, but we never saw it again.

At 0OOOI I was scrambled to investigate an unidentified object reported by acontrol tower operator at Haneda. The object was reported to be in the Tokyo bayarea in an orbit to the starboard at an estimated altitude of 5,000 feet. Iobserved nothing of an unusual nature in this area, however at 0016I when vectoredby Hi-Jinx on a heading of 320 degrees, and directed to look for a bogie at 1100o'clock, 4 miles, Lt Jones made radar contact at 10 degrees port 6000 yards. Thepoint moved rapidly from port to starboard and disappeared from the scope. I hadno visual contact with the target. Soon after this contact the search was aban-doned.I continued to search the Tokyo bay area independently until 0120I. Theweather was 3 to 4 cloud covered at an estimated altitude of 14,000 feet, withexceptional visibility of 60-70 miles. The only known air traffic at this time wasa C-54 in the pattern at Haneda and another C-54 over Johnson A.B., approximately30 minutes later.

At 0OOOI Lt Holder and I were scrambled to investigate an unidentified targetover Tokyo bay. Upon becoming airborne we immediately took up a heading for Tokyobay. At 0009I, Hi-Jinx reported a target at our 9 o'clock position. Visual contactwas made at 00101 with this target and identified as a C-54. We then started astarboard searching orbit under GCI control, southeast of Haneda A.B. At 0015I Hi-Jinx gave us a vector of 320 degrees. Hi-Jinx had a definite radar echo and gave usthe vector to intercept the unidentified target. Hi-Jinx estimated the target to beat 11 o'clock to us at a range of 4 miles. At 0016I I picked up a radar contact at10 degrees port, 10 degrees below at 6,000 yards. The target was rapidly movingfrom port to starboard and a "lock on" could not be accomplished. A turn to thestarboard was instigated to intercept target which disappeared on scope in approxi-mately 90 seconds. No visual contact was made with the unidentified target. Hi-Jinxwas then contacted and they were unable to give us another vector because they alsohad lost radar contact with the unidentified target. We continued our search overTokyo bay under Hi-Jinx control. At 0033I Hi-Jinx released us from scrambledmission. The only other aircraft intercepted during this mission was at 0100I. Thisaircraft was identified as a C-54 on course of 350 degrees altitude 5000 feat, speed180 knots. We noticed nothing of unusual nature from this time until we landed at0120I.

Statement of 1st Lt. G. S. Day, ADCC Controller at Johnson A.B.

At 2355I on 5 Aug 52, I scrambled one (1) F-94 alert aircraft to attempt tointercept and identify an unidentified aircraft or aerial object, reported to thisADCC through Shiroi GCI from visual sighting report by Haneda tower operators. Asreports of progress of intercept came into ADGC, I logged them in. A wire recordingof all reports was made, but due to conditions of communications and recorder, thisrecording is unreadable. By contacts were all made with Lt Albert, duty controllerat the Shiroi GCI station, also was controlling the F-94.

The F-94 was unable to close on the unidentified aircraft or object, aftergetting one radar contact from its reported locations; after a patrol search the F-94landed. My records show this sighting remains unidentified.

G. S. DAY1st Lt., USAFADCC Controller

Statement of 1st Lt Melvin K. Rawlins, Controller at Shiroi

At approximately 2330 hours, 5 Aug 52, while on duty as controller at Dot #4,528th AC&W Group, I received a call from the Haneda tower operator that they couldsee a bright light out over Tokyo Bay, northeast of their station at approximately1000 to 1500 feet. I relayed this information to ADCC and started checking for anindication on the radar scope on both high and low beam. There ware three (3) orfour (4) blips on low beam but none I could definitely get a movement on or none Icould get a reading on the HRI scope. At 2345 hours I was relieved by Lt Albert.

1st Lt Melvin K. Rawlins is stationed at Shiroi and is not immediately ava-ilable to sign narrative statement.

Statement of 1st Lt Henry E. Albert, Controller at Shiroi

The undersigned officer reported for work at Site #4, at 2345I, 5 Aug 52. Con-troller being relieved informed me of an unusual sighting reported to him by Hanedatower operator. This was reported to me as being a lighted object hovering north-east of Haneda. After discussion with ADCC controller, it was decided that an F-94should be scrambled to investigate.

At the time of scramble, I had what was believed to be the object in radar con-tact. The radar sighting indicated the object to be due south of this station overTokyo Bay and approximately eight (8) miles northeast of Haneda. The target was ina right orbit moving at varying speeds. It was impossible to estimate speed due tothe short distance and times involved.

Report of radar targets does not allow a plausable explanation ofthe nature or the targets. Absence or weather data, i.e. temperaturevs height and moisture vs height, does not allow an anomalous propa-gation estimate. However, the report states that targets did appear tobe permanent echos at various times.

5 August 1952 Haneda AFB, Japan

Description of Incident

The object was first noticed by two airmen walking across the ramp at Haneda AFB

on the night of 5 Aug 52 at 2330I(local time). The airmen were on their way to the

tower to relieve the operators. On reporting to the tower, the object was celled to the

attention of the tower operators who were going off duty.

The four operators agreed that the object, which they observed for from 50 minutes

to an hour through 7x50 binoculars, was circular in shape and with constant brilliance.

The light appeared to be a portion of a large, round, dark shape which was about 4

times the diameter of the light. When the object was close enough for details to be

seen, a smaller, less brilliant light could be seen along the lower edge of the dark

shape. The object faded to the east twice but reappeared; it could have faded or

actually gone away and come back. The size of the light, when closest to the tower, was

approximately the same as the ceiling balloons that are released near the tower. A

comparison was made to these 24' diameter balloons at 2000'. This would make the object

50' in diameter at 10 miles. During the observation, a lighted balloon was released

but this light was extremely dim and yellow compared to the object.

An airborne C-54 was requested to check the object, which the pilot did, but he re-

ported seeing only a star.

An AC&W unit was notified soon after the original visual sighting and shortly

after 2345I picked up an unidentified return. The object was tracked at varying

speeds from hovering to 300 knots. At 0012I the return "broke into three pieces" and

they maintained intervals of 1/4 mile. No visual observation was made from the AC&W

unit although it was attempted and, at one time, the object was within 10 miles of the

station. The radar was directed onto the target by visual observations from the tower.

So it can safely be assumed that both visual and radar contacts involved the same object.

CASE #3(contd)

At 003I an F-94 was airborne on a scramble and was requested to search to the NE

of Haneda AFB over Tokyo Bay. They could make no visual observations, but could see

the North Star and Venus. The F-94 was vectored to the object by GCI(both the F-94

and object were on the scope) and held of for 90 seconds. Shortly after this, both

the object and the F-94 disappeared into the ground clutter on the GCI. At no time

did the F-94 make visual contact. The radar contact indicated the target was at 6000

yards, 10 deg below and 10 deg to the right of a 320 deg bearing from the station. Soon after

loss of radar contact, the object was lost visually.

Comments

The F-94 crew reported excellent visibility, yet they could not visually observe

the object during a thorough search of the area. They stated that the moon was bright

and might possibly have caused reflections off the few scattered clouds. This, however,

is not in agreement with the description of an exceptionally bright light given by the

tower operators.

Since the weather was not given, it is not possible to determine whether the radar

return was caused by some type of anomalous propagation.

INCIDENT NO.5 - Shortly before midnight on August 5,1952, two airmen were walking toward the tower at HanedaAFB in Japan to begin their shift when the spotted a largeround object bearing a light in the sky. Hurrying to the tower,they pointed it out to the other tower operators, and theytook turns observing the object through 7x50 binoculars.Under the glasses, a less brilliant light could be seen aroundthe edge of the object. The tower people called radar andgave them a bearing on the thing, and radar picked up a tar-get in the immediate area. By correlating movement of theradar target and the visual UFO, they established that theywere both observing the same object. The radar tracked theobject at speeds varying from hovering to 300 knots. An F-94 was scrambled and vectored into the target. It got a ra-dar lock on and started to close on the object. At 6,000 yardsthe jet lost radar contact and at the same time the tower andground radar lost it, too. At the end of the sighting, the ob-ject as seen on the ground radar broke up into three pieceswhich flew formation at quarter-mile intervals. During theincident, a weather balloon was released at the base, and thewitnesses reported that its light was much dimmer than thatof the UFO. One of the puzzling aspects of the incident wasthat neither the jet pilot nor the radar crew was able to get avisual sighting on the object, although each was closer to ifthan the air base tower.
